I read on some threads that my dongle will work, just that you need to buy the license again. otherwise it’s fine.Depends how old motherboard is as maybe ipatched one. You can go on ebay look for used one thats said its cfw or if u want new look for old box and ask for serial to see if its patched
If it is indeed a burned component on the board you might be better off sending it to TronicsFix https://tronicsfix.com/collections/get-started/products/nintendo-switch-repairUPDATE! So my local game shop fixed the motherboard telling me it was burnt. I cant retrieve my Switch till tuesday however so i cant try it out. My question is, with a replaced motherboard, can I still use my Dongle and Tegra? (example SX OS) or should I just get a new Switch since the price of the repair is the same as a new one?
